Assembline SDR 17 2" Gasketed Water Pipe

[BruceWard]

I am hoping to install over 500' this weekend. In the past I have used schedule 40 but my plumber talked me into SDR 17 this time. Can anyone provide tips and explain the process of assembling this pipe. Thanks.

I have been plumbing a long time and this is the first I have heard of SDR 17. I have installed SDR 27. Is it a gasket in hub type pipe? If so, you use a lube made for that type fitting and just push them together. Making sure they bottom out. On 2" a shovel works pretty good just turned around and use it like a lever. If you make any turns be sure and block the 90 so they don't push off. Keep us up on your progress.

It is a gasketed pipe. My local supplier had SDR 21 and SDR 17. The SDR 17 is a heavier 250 PSI rated pipe.

My plumber said to use soap as the lubricant when joining the sections. I am not certain whether he really meant soap or was referring to special lube as soap.

 

[Kays Supply]

OK , you can use soap, but the supplier of the pipe should have a lube made for that. There will be alot of soap in your pipe by the time you lay that much. Be sure and rinse it good before using the water.

You got me thinking, so I looked it up. I lay much more sewer pipe than water pipe in the larger sizes. This site explains the SDR / Sch rating very well.Answer to PVC question - programs

We installed 500' today. It was as simple as cleaning the ends, coating the beveled end with lubricant and then two men pushing them together. Occasionally a joint did not want to seat. We placed a cap on the line and tapped with a hammer on 3 or so stubborn joints. My Dad and I assembled the 500' in a little over 2 hours. The next 150' will be through rock. I am leaving that until next week. Ill take some pictures and post them in the coming days.

Absolutley put in thrust blocks for ANY turn! That joint WILL come loose if not restrained.

Fortunately this was a straight run. We wiggled around a little but did not have any corners.

This is the pipe

And this is where the frist 500' were buried

And the hydrant to water the fruit trees.

The valve on the hydrant is a good idea. Be sure and make it where you can get to it without digging. Also a post of some kind to tie the hydrant to is a good idea. If you break the fitting behind the valve you are dry at the house until it is fixed. I usually put the hydrant farther from the main and use a piece of soft copper so it can move without breaking anything. Just a few points I have learned over the years. Some smaller gravel will help keep the mud from clogging your drain down hole.

 

[BruceWard]

Thanks for the tips. I bought a cover to go over the valve today and I plan to add some smaller gravel. I used the rocks to hold it up until the city inspects. I may hammer an iron pipe into the ground and tie the hydrant to it.

You won't regret it. A lawn mower or tractor can take one out pretty quick.

Has the city looked at it ? In Illinois you have to put a double check in the line or use a tank type hydrant.

 

[BruceWard]

The city asked for a dual check valve. There is a 3/4 Watts dual check valve ( 7 Bronze Dual Check Valves, Dual Checks / Dual Checks with Atmospheric Vent, Backflow Prevention - Watts ) installed in the line to the hydrant.

Hopefully the city will approve the dual check valve.

I couldn't see it in the picture, until I looked really close. Good for you. The one we use doesn't have a vent if installed below ground. Here it has to be servicable. That means without digging it up to work on it. That can be tricky.

 

[BruceWard]

The city approved the plumbing today.

The city installed the meter and connected my pipe yesterday. I blocked the end of the gasketed pipe run today. I placed 4 roughly 1'x1'x6" rocks at the end of the line, brought the line up with a 90, used another 90 to send it on toward the house, reduced to 1.5" pipe and installed a shutoff valve.

My plan is to slowly turn on the meter with the shutoff valve open to bleed the air and clean out the pipes. Then slowly close the shutoff valve while praying that the gasketed pipe stays together.

Does this sound right?

Here are a few pictures

And to work a tractor in

STOP, where you are. If I am seeing correctly, that is a DWV 90 on that pipe. That is NOT designed for city water pressure. It is for drain and vent. A pressure 90 has a socket for gluing at least twice that deep. I think the reducer is also DWV but can't see it well enough to be sure. If it holds now it won't for long.

They look like this.

Thanks I will replace them!

The tracer wire is a good idea. You may be glad you used it some day.
